A general term for birds in the family Picidae. Birds in this family are mainly adapted to living on tree trunks, with straight, strong, pointed beaks and tail feathers with hard rachises, short but powerful legs, and sharp claws. Most are 8-35cm long, but there are also large species that are nearly 60cm long. Many species have a combination of two or three colors in their plumage, such as black, white, red, green, yellow, or brown, and the main difference between males and females is the color of their heads. Most species live alone in forests in pairs, perching vertically near the base of tree trunks and feeding while climbing straight or in a spiral, then flying off to the trunk of another tree when they have reached the top.
